Embodiment

Embodiment 1, as shown in Figure 1, when rocking handle 15 when pressing down, left piston 3 moves upward, the water of left piston 3 upsides is upwards carried, opened left inlet valve 5 thereby form the vacuum suction in the left piston cylinder body 4, well water enters inlet water tank 8 by water inlet manifold 7 and enters in the left piston cylinder body 4 through left piston cylinder body water intake 6; Right piston 12 moves downward, and forces right water inlet valve block 10 to be closed, and the water in the piston/cylinder 18 is washed right piston valve block 11 open, and water enters above the right piston, thereby the water level in the header tank 13 is increased, and water is discharged by water outlet 16.

In like manner, when rocking handle 15 is upwards carried, right piston 12 moves upward, the water of right piston 12 upsides is upwards carried, right piston valve block 11 is closed, thereby form the vacuum suction in the right piston/cylinder 18 and open right piston valve block 10, well water enters inlet water tank 8 in right piston/cylinder water intake 9 enters right piston/cylinder 18 by water inlet manifold 7; Left piston 3 moves downward, and forces left side water inlet valve block 5 to be closed, and the water in the left piston cylinder body 4 is washed left piston valve block 2 open, and water enters above the left piston, thereby the water level in the header tank 13 is increased, and water is discharged by water outlet 16.

Hence one can see that, and rocking handle 15 is no matter be can both make water outlet 16 drainings to pressing down or upwards carrying, thereby improved working efficiency.

Embodiment 2, by Fig. 2-6 as can be known, piston 3 and right piston 12 be not for establishing the solid piston of through hole, when rocking handle 15 when pressing down, left piston 3 moves upward, thereby form the vacuum suction in the left piston cylinder body 4 and open left side water inlet valve block 5, well water is entered inlet water tank 8 by water inlet manifold 7 water-inlet cavity 30 enters in the left piston cylinder body 4 through left piston cylinder body water intake 6; Right piston 12 moves downward, force right water inlet valve block 10 to be closed, water in the right piston/cylinder 18 is under pressure, thereby make water in the right piston/cylinder 18 after right piston/cylinder water outlet 39 enters right chamber 32, wash right clapboard valve block 27 on the right swash plate 29 open in right clapboard osculum 28 enters water chamber 33, hydraulic pressure in the water chamber 33 forces the left clapboard valve block 26 on the left swash plate 24 to be closed, water in the water chamber 33 can only be discharged by titting water outlet 21, at this moment, hydraulic pressure in the water chamber 33 is bigger, thereby water can be delivered to higher position.

In like manner, when rocking handle 15 was upwards carried, right piston 12 moved upward, and opened right water inlet valve block 10 thereby form the vacuum suction in the right piston/cylinder 18, and well water is entered the water-inlet cavity 30 of inlet water tank 8 in right piston/cylinder water intake 9 enters right piston/cylinder 18 by water inlet manifold 7; Left piston 3 moves downward, force left side water inlet valve block 7 to be closed, water in the left piston cylinder body 4 is under pressure, thereby make water in the left piston cylinder body 4 after left piston cylinder body water outlet 38 enters left chamber 34, wash left clapboard valve block 26 on the left swash plate 24 open in left clapboard osculum 25 enters water chamber 33, hydraulic pressure in the water chamber 33 forces the right clapboard valve block 27 on the right swash plate 29 to be closed, water in the water chamber 33 can only be discharged by titting water outlet 21, at this moment, hydraulic pressure in the water chamber 33 is bigger, thereby water can be delivered to higher position.

Hence one can see that, and rocking handle 15 can be delivered to water higher position, thereby improve working efficiency no matter be to pressing down or upwards carry the water that can both make the titting water outlet draining certain pressure to be arranged.

Embodiment 3, in embodiment 2, between inlet water tank top cover 23 and inlet water tank 8, be set with seal washer 22, be respectively equipped with on the seal washer 22 and the left packing ring water outlet 44 of the left piston cylinder body water outlet 38 of inlet water tank top cover 23, left inlet water tank water outlet 6, right piston/cylinder water outlet 39 and right inlet water tank water outlet 9 corresponding cooperations, left packing ring water intake 40, right packing ring water outlet 42 and right packing ring water intake 41, thereby make it can reach job requirement, also make it to seal better.
